Calif. nursing student was murdered by friend, prosecutors say

A Northern California jury found 28-year-old Giselle Esteban guilty of first-degree murder on Oct. 29, 2012, in the gruesome death of her former friend and California nursing student, Michelle Le. Prosecutors said Esteban attacked Le on May 2011 in the parking garage of the hospital where Le was doing a clinical rotation. Police and volunteer searchers discovered her badly decomposed remains in a canyon east of San Francisco Bay after she was missing for months.
